In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The television system that the embodiment of the invention provides can be adjusted image model and acoustic pattern automatically according to people's facial expression, realizes the interaction of people and TV automatically, brings more humane experience to the user.
Fig. 1 shows the structural principle of the interactive television system that the embodiment of the invention provides, and for convenience of explanation, only shows part related to the present invention.
In embodiments of the present invention, described interactive television system comprises:
Image acquisition units 1, this image acquisition units 1 is used for images acquired, and will export after the image encoding that collect;
Result treatment unit 4, this result treatment unit 4 is according to the corresponding program of expression parameter call of described face identification unit 3 outputs, to the TV executable operations; And
Central control unit 5, this central control unit 5 receives the data of image acquisition units 1, graphics processing unit 2, face identification unit 3 and 4 outputs of result treatment unit, and sending controling instruction control image acquisition units 1, graphics processing unit 2, face identification unit 3 and result treatment unit 4.
As one embodiment of the present invention, image acquisition units 1 comprises camera head 11; Graphics processing unit 2 comprise with coloured image be converted to gray level image gray scale processing module 21, the gray level image of described gray scale processing module output is carried out histogram analysis module 22 that threshold value cuts apart and will carry out the binary conversion treatment module 23 that gray level image that threshold value cuts apart is converted into black and white image by described histogram analysis module.Face identification unit 3 comprises people's face detection module 31 that whether has people's face figure in the detected image and the facial feature extraction module 32 that facial image is expressed one's feelings and judged; Result treatment unit 4 comprises that the happiness program module 41, control image model and the acoustic pattern that strengthen image model and acoustic pattern are the gentle program module 42 of median and weaken image model and the dejected program module 43 of acoustic pattern; Central control unit 5 comprises processor 51 and memory 52.
Below in conjunction with specific embodiment realization of the present invention is elaborated.
Start image acquisition units 1 behind the television startup, object before 11 pairs of television sets of camera head carries out IMAQ, 24 true color images that image acquisition units 1 will collect are encoded according to certain picture format, and the image after will encoding is stored on the memory 52 in the central control unit 5.Processor 51 in the central control unit 5 carries out gray processing according to the 21 pairs of image encoded of gray scale processing module in the system program control graphics processing unit 2 to be handled, carry out histogram analysis by 22 pairs of images of handling through gray processing of histogram analysis module again, obtain an appropriate threshold, this threshold value is used for that gray level image is carried out threshold value and cuts apart, and after will carrying out binary conversion treatment by binary conversion treatment module 23 through the gray level image that threshold value is cut apart, the binaryzation data are sent to memory 52 in the central control unit 5, finish the process that coloured image is converted into the bianry image of black and white this moment.31 pairs of these bianry images of people's face detection module that processor 51 in the central control unit 5 is controlled after receiving the binaryzation data in the face identification unit 3 carry out the facial image detection, judge whether this image exists facial image, if there is facial image, extract the position and the shape of people's face face by facial feature extraction module 32, provide algorithm by 5 processor 51 in the central control unit, judge people's expression according to human face's feature, expression can be divided three classes: the smiling face, normal and bitter face, the mood of smiling face's correspondence can be understood as happiness, normal corresponding mood can be understood as gentle, and the mood of bitter face correspondence can be understood as dejected.And the data of will expressing one's feelings feed back to the processor 51 in the central control unit 5, and processor 51 according to recognition result, calls corresponding program module according to system program control result treatment unit 4.
When the human face expression that recognizes was the smiling face, result treatment unit 4 calls carried out happiness program module 41, strengthens the image model and the acoustic pattern of TV; When the human face expression that recognizes is just often, result treatment unit 4 calls carries out gentle program module 42, and control television image pattern and acoustic pattern are median; Result treatment unit 4 calls when the human face expression that recognizes is bitter face, carries out dejected program module 43, weakens the image model and the acoustic pattern of TV.
As a realization example of the present invention, strengthening image model and acoustic pattern includes but not limited to: to strengthen contrast and brightness, adjustment tone be warm tones, increase colored concentration, promote clearness, improve the size of volume, strengthens supper bass, promotes high pitch, opens surround sound.Image model and acoustic pattern are that median includes but not limited to: adjustment contrast, brightness are relatively more suitable median, and adjusting tone is that normal tone, the colored concentration of reduction are that normal colour, definition are adjusted into the median that relatively is fit to; The acoustic pattern aspect includes but not limited to that reduction volume to comparatively suitable median, reduction supper bass is comparatively suitable median, median, the unlatching surround sound that the reduction high pitch is extremely comparatively suitable.Weaken image model and acoustic pattern includes but not limited to: reduce contrast, brightness is lower value, adjustments tone is cool tone, reduce colored concentration, reduce definition for lower value, reduce volume to smaller value, reduce supper bass and be smaller value, reduce the extremely smaller value of high pitch, close surround sound.
